This idea does make sense, and there have been several studies on it. Two examples: 1. Cummings et. al, (2006). Auditory semantic networks for words and natural sounds, Brain Research, 1115, 92-107. 2. Lebrun et al. (2001). An ERD mapping study of the neurocognitive processes involved in the perceptual and semantic analysis of environmental sounds and words. Cognitive Brain Research, 11, 235-248. In general the process they used didn't distort meaningful sounds, but measure the meaningfullness of the sounds, and then pick sounds that are on opposite ends of the scaleing results.
